HYBRID-HIGH RELIABILITY
RADIATION HARDENED
DC-DC CONVERTER
M3G-SERIES
28V Input, Triple Output
Description
The M3G-Series of DC-DC converters are radiation
hardened, high reliability converters designed for
extended operation in hostile environments. Their small
size and low weight make them ideal for applications
such as geostationary earth orbit satellites and deep
space probes. They exhibit a high tolerance to total
ionizing dose, single event effects and environmental
stresses such as temperature extremes, mechanical
shock, and vibration.
The converters incorporate a fixed frequency single
ended forward topology with magnetic feedback and
an internal EMI filter that utilizes multilayer ceramic
capacitors that are subjected to extensive lot screening
for optimum reliability. These converters are capable
of meeting the conducted emissions and conducted
susceptibility requirements of MIL-STD-461C without
any additional components. External inhibit and
synchronization input and output allow these converters
to be easily incorporated into larger power systems.
They are enclosed in a hermetic 3" x 2" x 0.475" package
constructed of an Aluminum-Silicon-Carbide (AlSiC)
base and an Alloy 48 ring frame and they weigh less
than 110 grams. The package utilizes rugged ceramic
feed-through copper core pins and is sealed using
parallel seam welding.
Manufactured in a facility fully qualified to MIL-PRF-
38534, these converters are fabricated utilizing DLA
Land and Maritime qualified processes. For available
screening options, refer to device screening table in the
data sheet.
Non-flight versions of the M3G-Series converters are
available for system development purposes. Variations
in electrical specifications and screening to meet custom
requirements can be accommodated.

Notes: Electrical Performance Characteristics
1. Parameter is tested as part of design characterization or after design changes. Thereafter, parameter shall
be guaranteed to the limits specified.
2. Parameter verified during line and load regulation tests.
3. Although operation with no load is permissible, light loading on the main (+5 volt) output may cause the output
voltage of the auxiliary outputs
(±12 volt or ±15 volt) to drop out of regulation. It is therefore recommended that at least 200 mA or 20 percent
of the total output power, whichever is greater, be taken from the main (+5 volt) output.
4. Although operation with no load is permissible, heavy loading on the main (+5 volt) output may cause the
output voltage of the auxiliary outputs
(±12 volt or ±15 volt) to rise out of regulation. It is therefore recommended that at least 50 mA or 20 percent
of the total output power, whichever is greater, be taken from the auxiliary (±12 volt or ±15 volt) outputs.
5. Unless otherwise specified, “Rated” load is 20W on the main (+5 volt) output and 10 watts each on the auxiliary
(±12 volt or ±15 volt) outputs. Load currents of up to 5A and ±1A on the main and auxiliary outputs respec-
tively are acceptable as long as the total output power does not to exceed 40 watts.
6. Guaranteed for a D.C. to 20MHz bandwidth. Tested using a 20KHz to 10MHz bandwidth.
7. Capacitive load may be any value from 0 to the maximum limit without compromising dc performance.
A capacitive load in excess of the maximum limit may interfere with the proper operation of the converter’s
overload protection, causing erratic behavior during turn-on.
8. Overload power dissipation is defined as the device power dissipation with the load set such that VOUT = 90%
of nominal.
9. Load step transition time ³ 10 µs.

12. Turn-on delay time from either a step application of input power or a logic low to a logic high transition

13. Load is varied for output under test while the remaining outputs are loaded at 50% of rated. Regulation relative
to output voltage at 50% rated load.
14. Although operation at temperatures between +85°C and +125°C is guaranteed, no parametric limits are
specified.

Application Note:
A) Attachment of the Converter
The following procedure is recommended for mounting the converter for optimum cooling and to circumvent
any potential damage to the converter.
Ensure that flatness of the plate where M3G converter to be mounted is no greater than 0.003” per linear inch.
It is recommended that a thermally conductive gasket is used to promote the thermal transfer and to fill any
voids existing between the two surfaces. IR recommends Sil-Pad 2000 with the thickness of 0.010". The
shape of the gasket should match the footprint of the converter including the mounting flanges. The gasket
is available from IR. The M3G-series converter requires either M3 or 4-40 size screws for attachment
purposes.
The procedure for mounting the converter is as follows:
1. Check the mounting surfaces and remove foreign material, burrs if any or anything that may
interfere with the attachment of the converter.
2. Place the gasket on the surface reserved for the converter and line it up with the mounting holes.
3. Place the converter on the gasket and line both up with mounting holes.
4. Install screws using appropriate washers and tighten by hand (~ 4 in·oz) in the sequence shown below.
5. Tighten the screws with an appropriate torque driver. Torque the screws up to 6 in·lb in the sequence
shown above.
